- Ready to use 1.25 mmol/L stablized chromogen solution
- Metabolism of the TMB substrate by HRP creates a soluble, bluish reaction product that may be quantified by measuring absorbance at 370 or 665 nm.
- Reaction can be stopped by addition of 1 volume of 1N hydrocloric or sulfurc acid to yield a yellow reaction product that can be measured by absorbance at 450 nm (within one hour).
